Australia demands declaration of pornography upon entry

The government of Australia has began demanding that all people who travel to that country declare if they have any pornography in their possession. If a person answers that they have, that is grounds enough to have the customs search your belongings. Some people have speculated that this idiotic law was created to safeguard children from child pornography; however, nowhere will anybody be asked about child pornography, only about pornography in general. This goes to further show that governmental laws against child pornography are nothing more than a way to demonise sex and to put people in prison (not only do they not protect children, but they actually do a lot of harm to many minors).

Many people will likely lie, and answer 'No' to the question, especially if they are traveling with their family, or if the pornography they are bringing has been created by them for personal consumption. This will, of course, mean that they will be breaking the law by lying on their declaration.

Questions

Questions we should be asking ourselves include:

Will children be asked that question and if so what will be the consequences for them if they lie or answer 'Yes'?

Will the term "pornography" be defined for people before they answer such a question?

Why is the term "pornography" used by the customs, when that specific term was not part of the law that is supposedly being applied?

Why is pornography considered something harmful to the society?

What safeguards will be put into place to protect people's privacy? And who will be responsible for enforcing those safeguards?

What is to ensure that the customs agents will not use their personal prejudices against non-criminal sexual preferences and harrass people who have pornography depicting those sexualities?
